Open png image?

luckcfm · September 30, 2019, 3:16pm

I’m starting to use micropython and I want to load a stored png image, I tried with

img = lv.img(scr)
img.set_src("./back.png")

But had no success, can somebody please show me an example on how to do with?

Thanks in advance.

Answering my own question, I found this and its working ok!

github.com

littlevgl/lv_binding_micropython/blob/master/examples/example2.py


# init

import ustruct as struct

import lodepng as png
import lvgl as lv
lv.init()
lv.log_register_print_cb(lambda level,path,line,msg: print('%s(%d): %s' % (path, line, msg)))

import SDL
SDL.init()

# Register SDL display driver.

disp_buf1 = lv.disp_buf_t()
buf1_1 = bytes(480*10)
lv.disp_buf_init(disp_buf1,buf1_1, None, len(buf1_1)//4)
disp_drv = lv.disp_drv_t()
lv.disp_drv_init(disp_drv)
